Abstract

A method for unlocking a steering system that includes detecting and validating an identity input. After the identity input is validated a vehicle start command is detected and thereafter a steering assist mechanism is enabled. Once the steering assist mechanism is enabled, a force is applied to a steering column utilizing the steering assist mechanism. Following an application of the force by the steering assist mechanism, the steering system is unlocked by an unlocking mechanism. After unlocking of the steering system, a vehicle may then be started. The application of the force to the steering column may be alternating application of a clockwise and counterclockwise torque or may be a directional torque applied to the steering column based on a measured steering characteristic.
